I'm reading about holocaust denial after a fellow at Rough Edges gave me one of their pamphlets. Holocaust deniers, who are mostly just neo-Nazis, basically seem to be saying that "we didn't kill six million Jews but we would if we could." They feign horror at the suggestion that Hitler would ever harm a hair on a Jewish head, but then talk about how awful Jewish people are and if they were slightly harmed they totally had it coming.
But it's interesting to read about all the myths (accepted as myths by both sides) that I remember as being historical facts when I went to Germany as a kid. I thought most of the killings happened in Germany for instance. But it seems that nearly all of them happened in Poland, because German people got upset at Hitler when he tried to mass kill people in Germany. And Nazis didn't make soap out of concentration camp victims either.
I know it's difficult to care about fact-checking when you're dealing with folk like the Nazis, but I suspect if the Allies had been a bit more careful about the rumours that were spread, there probably wouldn't be such a successful Holocaust denial industry today.
